It’s a homemade sextravaganza that Kanye West wishes would just go away. The Grammy-winning rap star is terrified that a sex tape featuring the “Sin City” rapper is up for grabs, RadarOnline.com reports. But a porn mogul willing to pay millions for the tape has cast doubt on its legitimacy. “We’ve heard rumors for a couple of years about this tape being available, Steven Hirsch founder and co-CEO of Vivid Entertainment told The News. “I’m not even sure if it is real. If in fact it was, it would sell extremely well. He is a huge star.” According to Radar, the video was shot sometime shortly before West started dating  bootylicious reality star Kim Kardashian— who became famous for starring in her own “leaked” sex tape. “The Kanye sex tape is being shopped right now and there’s a lot of interest, but Kanye is freaking out,” a porn industry insider told the gossip website. “He doesn’t want this tape out and will do anything to make sure it stays private,” said the source. “In my expert opinion, Kanye’s performance far outweighs Kim’s.” Hirsch — who made millions when he distributed Kardashian’s amateur celluloid romp — said if it is real, he would pay more than $2 million for West’s tape. “We would have to see the tape and the quality,” he said. “If it was really good, we would do everything in our power to buy it.” In the sex tape — which Radar insists is real — a woman who looks like Kardashian identifies herself as over 18 years old and confesses that she is married but claims, “My husband and I don’t have sex anymore . . . that’s why I’m here!” During the couple’s steamy sex romp, they never kiss and don’t interact any further than simply doing the deed, in various positions throughout and with Kanye wearing a condom. “Celebrity women who are in sex tapes do better than men celebrities,” Hirsch said. “But Kanye is different. He is a huge rock star. This is a guy that everyone in the world knows and I think people would be interested. I don’t think it’s a huge scandal, but I think it’s a huge seller.” Reps for West declined to comment. NY Daily
